1. A communication device, comprising:
a memory storing a relationship between a plurality of cellular configurations for a cellular modem and a plurality of control effort values, each of the plurality of control effort values associated with a respective operating characteristic of the cellular modem; and
processing circuitry coupled to the memory, the processing circuitry configured to:
receive an operating characteristic of the cellular modem operating in a first cellular configuration of the plurality of cellular configurations;
receive a threshold from a power controller;
determine a control effort value based on the operating characteristic, the threshold, and a control function;
determine a second cellular configuration of the plurality of cellular configurations based on the control effort value and the relationship between the plurality of cellular configurations and the plurality of control effort values; and
transmit a first control signal indicative of the second cellular configuration to the cellular modem that causes the cellular modem to operate in the second cellular configuration.
